Spending time:
How long does it take you to stydy English?
How long does it take you to get up in the morning?
How much time do you spend to have breakfast?
How much time do you spend to get to work?
Wasting time:
Do you think watching Tv is a waste of time?
Do you think playing sports is a waste of time?
Do you think doing housework is a waste of time?
Do you think cooking is a waste of time?
Do you think reading newspapers is a waste of time?
My opinion:
My opinion about these topic is very simple. All the activities are useful but we have to spend less time in some activities to spend in some others. For example we have to spend less time watching TV and we have to spend more time playing sports.
